  • 1940: “These mechanical monstrosities lack the intuitive check of a human mind. A mathematician can spot a stray digit through reason; a machine will blindly process an error to its conclusion. We are trading the elegance of thought for a noisy, fallible crate of glass and wire.”

    1950: “Direct control is the only honest way to command a machine. If you cannot visualize the specific vacuum tube you are firing, you aren’t truly programming. To delegate this to any intermediary is to invite a loss of precision that the hardware simply cannot afford.”

    1955: “These ‘mnemonics’ are a crutch for the lazy. By using words instead of addresses, the programmer loses the vital ‘feel’ for memory layout. We are seeing a five-fold decrease in efficiency; no automated assembler can ever match the tight, hand-calculated loops of a master of bits.”

    1965: “Compilers are the death of performance. These languages allow ‘programmers’ who don’t even understand the CPU architecture to bloat memory with generic subroutines. Software is becoming a black box—impenetrable, unoptimized, and dangerously detached from the reality of the silicon.”




  • Being a particularly dumb fellow layman but seeing no other comments after 18h…

    I’m picturing a ruler thrown into gravity waves and another ruler somehow measuring the parts of the first one where millimeter markers stop being one millimeter apart.

    Now for Gemini’s summary:

    Space-based gravitational wave detection is the study of ripples in spacetime using observatories positioned in orbit rather than on Earth. While ground-based detectors like LIGO and Virgo have already proven these waves exist, they are limited by their size and Earth’s seismic “noise.”

    How It Works

    Space-based detection uses laser interferometry across millions of kilometers of vacuum.

    • The Formation: LISA will consist of three spacecraft flying in a triangular formation, roughly 2.5 million kilometers apart, orbiting the Sun behind the Earth.

    • The “Arms”: Each spacecraft contains “test masses” (gold-platinum cubes) that float freely in a vacuum, shielded from solar wind and radiation.

    • The Measurement: Lasers are fired between the spacecraft to monitor the distance between these cubes. When a gravitational wave passes through the formation, it causes the fabric of space to stretch and squeeze, changing the distance between the cubes by a fraction of an atom’s width.

    … Honestly I’m feeling reasonably good about my dummy understanding. The “rulers” are lasers being shot between satellites all around the Earth, but I think it sounds roughly right?







  • LAN tester.

    I thought of it as fancy electrician / network equipment. Not anymore. Now it’s basic troubleshooting / procedure.

    On a particularly frustrating switch installation, I picked one up for like $20 on Amazon, and it’s made me much less annoyed by network changes.

    For context, I’m one of those people who hoards any electronic bits that might prove useful on a hobby project later, so lots of old patch cables and cable reels with unknown breaks, so maybe a LAN tester is really only worth it for others like that, but I’d recommend it to any level of tech enthusiast at least.
